Warren Buffett tweets, Internet listens

If one tweet can roil the stock markets, think of what one tweet from Warren Buffett could do.

The 82-year-old guru of the financial world now has a Twitter account and sent out his first tweet this morning to promote a live online interview with Fortune magazine on “Women, Work, and Other Wisdom.”

Within an hour of that one (and so far only) “Warren is in the house” tweet, @WarrenBuffett had nearly 65,000 followers and had been re-tweeted nearly 12,000 times.

The Berkshire Hathaway chairman and CEO also pens an essay for the magazine’s upcoming Fortune 500 edition (but already available online) on how women in business are the key to America’s future prosperity.

During the conversation, Buffett was asked to define success. His answer: “If the people that you want to have love you, love you, you’re a success.”

Buffett immediately became a trending topic on Twitter, but some in the Twittersphere noted that he’s not new to technology. In this video clip, he noted that he plays bridge online about 12 hours a week and also used YouTube to listen to music.
